All users of imgdownload() require registration of the image, so make
registration an integral part of imgdownload() itself and simplify the
"action" parameter to be one of image_select(), image_exec() et al.

There is no need to explicitly call basename() to construct an image
name in imgfetch_core_exec(), since image_set_uri() will do so
automatically anyway (and will do so without getting confused by URIs
with query strings).

Refactor the {load,exec} image operations as {probe,exec}. This makes
the probe mechanism cleaner, eliminates some forward declarations,
avoids holding magic state in image->priv, eliminates the possibility
of screwing up between the "load" and "exec" stages, and makes the
documentation simpler since the concept of "loading" (as distinct from
"executing") no longer needs to be explained.

The online documentation (e.g. http://ipxe.org/cmd/ifopen), though not
yet complete, is far more comprehensive than could be provided within
the iPXE binary. Save around 200 bytes (compressed) by removing the
command descriptions from the interactive help, and instead referring
users directly to the web page describing the relevant command.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

This resolves potential difficulties occurring when more than one script
is used. Total cost: 88 bytes uncompressed.

Having a default script containing
#!gpxe
autoboot
can cause problems when entering commands to load and start a kernel
manually; the default script image will still be present when the
kernel is started and so will be treated as an initrd. It is possible
to work around this by typing "imgfree" before any other commands, but
this is counter-intuitive.
Fix by allowing the embedded image list to be empty (in which case we
just call autoboot()), and making this the default.

If there is more than one loaded image, refuse to automatically select
the image to execute. There are at least two possible cases, with
different "correct" answers:
1. User loads image A by mistake, then loads image B and types "boot".
User wants to execute image B.
2. User loads image A, then loads image B (which patches image A), then
types "boot". User wants to execute image A.
If a user actually wants to load multiple images, they must explicitly
specify which image is to be executed.
We can just treat all non-kernel images as initrds, which matches our
behaviour for multiboot kernels. This allows us to eliminate initrd as
an image type, and treat the "initrd" command as just another synonym for
"imgfetch".
